A sieve.
Prime numbers are not invented.
Eratosthenes lived between 276 and 194 B.C. He didn't discover prime numbers; he devised a simple way to determine what numbers are prime in a given range.
composite numbers
The Sieve of Eratosthenes filters numbers, letting the composites fall through while the primes remain.

Eratosthenes, It says it is Eratosthenes.
Prime numbers are not invented.
The algorithm for identifying prime numbers which is known as the Sieve of Eratosthenes has been accepted as accurate for thousands of years.

Eratosthenes' method of finding prime and composite number is called 'The Sieve of Eratosthene'.
It is called a sieve.

No, although he did devise a way to predict them.
